LIGHTING FIXTURE.

Application filed March 17, 1923. Serial No. 625,845.

To all whom it may concern: I

Be it known that I, ABRAHAM Coornn, a citizen ofthe United States,residing in the borough of Brooklyn, county of Kings, city and State ofNew York, have invented an Improvement in Lighting Fixtures, of whichthe following is a specification.

. My present invention relates to a lighting fixture and moreparticularly to a reversible socket construction for use in connectiontherewith. In lighting fixtures as commonly constructed one or more lampsockets maybe employed, and heretofore a lamp socket shell has been usedfor each lamp and in certain types of fixtures ornamentalcollars havebeen associated with the lamp socket shells. So far as I am aware,howover, these lamp socket shells and the ornamental collars or handshave been'so constructed that in any instance the shell and ornamentalcollar are adapted to be associated with each other in but onepredetermined relationship. Consequently the ornamental collars havebeen designed in some instances to receive and support lamp shades andin other instances have been so designed that a ball bulb of colored orfrosted glass or other material has been employed without the use of thelamp shade. Oftentiines a fixture in which the lamp shades are employedappeals to a purchaser vith the exception of the lamp shade attachincntsin whichinstance the purchaser prefers the ball bulb attachments.Obviously also the reverse of this condition sometimes occurs. In eitherevent it is necessary to provide a fixture constructed to satisfy thepurpose of the purchaser and this necessitates the manufacture of thesocket shells and ornamental collars to meet the demand in each case.The object of my present invention is to overcome this difficulty,making it possible to reverse the position of the ornamental bands andto construct the socket shells to receive the ornamental bands in eitherof their reversible positions. Obviously this makes a simple matter ofsatisfying the demands of the purchaser in this particular respect andin regard to any given fixture in which these devices are employed.

In carrying out the invention, therefore, I employ a socket shell,together with an ornamental collar or band adapted to be connected tothe socket shell iii either of two reversible positions so that in oneposition a shade may be employed with and supported by the ornamentalcollar and in the other 1 position aball bulb may be used, as will behereinafter more particularly described.

. In the drawing:

4 Fig. 1 is a central longitudinal section 0 the parts of a lightingfixture to which my invention particularly relates.

Fig. 2 is an inverted or bottomplan of the parts as shown in Fig. 1.

Fig. Sis a view similar to Fig. 1 showing the ornamental ring in itsreversed position and with a lamp shade attached thereto, and Fig. 4 isa plan of the open end of the socket shell.

Referring more particularly to the drawing, the parts of a lightingfixture to which my present invention relates include a socket shell 10which is preferably made of brass or any other suitable material and iscylindrical, having an opening 11 at one end for the passage of the leadwires to the socket and for attachment to a suitable support, while atthe opposite end there is preferably provided a bead indicated at 12.Adjacent the beaded end 12 of the socket shell there is acircumferential rib 13 of appreciably greater diameter than that of thecylindrical body portion thereof for a purpose to be hereinafterdescribed. This socket shell as is customary is adapted to receive theusual electriclamp socket as indicated in dotted lines at 14 in Fig. 1 I

i The parts of the invention also include a collar or band member 15which is adapted to be associated with and supported by the socket shelland as illustrated is curved in cross section and provided with acircular flange preferably extending from the convex surface thereof andin a position intermediate of the inner and outer peripheries of thecollar so as to be of an appreciably greater diameter than the diameterof the socket shell. It will be understood that either interiorly orexteriorly, or both interiorly and exteriorly, this collar or bandmember may be ornamented or embellished in any desired manner. Inpredetermined positions also the flange 16 is provided with bosses 17 ineach of which there is a tapped opening to receive a thumb screw 18adapted to engage the outer surface of a lamp shade 19 to secure thesame in position Within the flange in the customary manner.

As will now be apparent the ornamental collar may be fitted on thesocket shell in the position shown in Fig. 1 so that the inner edge ofthe collar slides over the rib 13 and abuts against the bead 12, theparts Being frictionally engaged to maintain their relationship, inwhich instance the fixture is adapted to receive the usual ball bulb offrosted or colored glass that are commonly employed. It will also beapparent, as indicated in Fig. 3, that the ornamental collar may beassociated with the socket shell in the reversed position in which theinner edge of the collar bears against the rib 13 and the beads againstthe outer surface of the inner portion of the collar to frictionallymaintain the parts in position and the ornamental collar employed tosupport a lamp shade also in the customary manner. In either instance,it will now be apparent that in placing the ornamental collar inposition on the socket shell the body of the shell is of a suiiicientlysmall diameterto pass through the opening in the ornamental collarwithout coming into contact therewith and consequently without marringor injuring in any manner the surface of the socket shell which, as willbe understood, may be finished in the usual or any desired manner, thisbeing the purpose of providing the rib 13 and making the same of anappreciably greater diameter than the diameter of the body of the socketshell.

I claim as my invention: 7

1. In a lighting fixture, a socket shell, a collar carried by the saidsocket shell in either one of two reversible positions, and meansassociated with the collar and adapted to support a lamp shade when thecollar is in one of its reversible positions, the socket shell beingadapted to receive a ball bulb when the collar is associated therewithin its other reversible position.

2. In a lighting fixture, a socket shell having at one end thereof aportion of appreciably greater diameter than the diameter o-fthe body ofthe shell, a collar adapted to engage the enlarged portion of the socketshell in either one of two reversible positions, and a device associatedwith the collar and adapted when the collar is in one of its reversiblepositions to support aolamp shade, the said socket shell being adaptedto receive a ball bulb when the collar is associated therewith in itsother reversible position.

, 8. In a lighting fixture, a socket shell having at one end thereof arib of appreciably greater diameter than the diameter of the body of theshell, a collar adapted to engage the said rib on the socket shell ineither oneof two reversible positions, and a flange extendingintermediate of the inner and outer peripheries of the collar with theflange uppermost in one of its positions when a ball bulb may be usedwith the socket shell and with the flange lowermost in the otherposition to supporta lamp shade.

4. In a lighting fixture, a socket shell having at one end thereof a ribof appreciably greater diameter than the diameter of the body of theshell, a collar member of curved cross section adapted to engage the ribon the socket shell in either one of two reversible positions, and aflange extending from the convex surface of the collar intermediate ofthe inner and outer edges thereof so that when the flange is in anuppermost position a ball bulb may be used with the socket shell andwhen the flange is in its lowermost position it is adapted to support alamp shade;
